可网络化管理的高精度多路数控直流电源

Digital-controlled multi-loop of high-precision DC power supply with network manageability

介绍了一款以AT89C51单片机为核心的新颖的直流稳压电源的设计.该电源能同步输出正负电压值,通过电源面板键盘对电压值的预置和步进调节实现独立工作,也可通过PC机的“虚拟键盘”实现远程控制和网络化管理.系统具有通用性好、可靠性高、线路简单、步进精度高、显示直观、使用方便等优点,有较高的性价比.

A novel design of high-precision DC stabilized power supply based on microcontroller AT89C51 was introduced. The power supply, which can output positive and negative voltage synchronously, was realized independence work through preliminary voltage values setting and step-by-step regulation on panel keyboard. Remote control and network management by PC＇s virtual keyboard can be also realized advantages such as versatility, higher reliability, simpler circuit, higher step precision, directly perceived, convenient in operation and good function with low price were considered among the novel design.
